Description
Technical field
The invention belongs to medicine Magnetic testi fields, and in particular to a kind of Nei Tan formulas biological tissue magnetic distribution map measuring method with
Device.
Background technology
Cell, tissue or the organ of organism, such as the heart, brain, flesh, stomach, retina etc. can generate bioelectrical signals, bag
Include resting potential and action potential.In the state of peace and quiet, the charged ion being present in inside and outside cell membrane is unevenly distributed cell,
Potential difference is formed, is known as resting potential.When cell is stimulated, the ion inside and outside film can react, and current potential can change,
Form action potential.Bioelectricity can be formed during above-mentioned potential change, bioelectricity can generate biological magnetic field.When some portion of human body
When lesion occurs for position, vivo biodistribution electric current and human magnetic field will change, for example, the magnetic of normal bio tissue and cancerous tissue
Figure is different;Normal magnetocardiogram, magneticencephalogram, flesh magnetic chart and magnetic chart during illness are also different.In short, in human body Different Organs or group
The magnetic signal of acquisition is knitted, can assist a physician the diagnosis cause of disease, have higher clinical reference value.For example, magnetocardiogram can be used
Myocardial ischemia, confirmation coronary heart disease, confirmed myocardial necrosis etc. are found in antidiastole, and magnetogastrogram can be used for diagnosis gastrointestinal disturbances and move
Power, diagnosis ulcer and observation drug are to the therapeutic effect of stomach functional disease.
In many medical diagnosis, magnetic chart is than the information contained by map of current more accurately, more comprehensively.With electrocardiogram and magnetocardiogram
Exemplified by, electrocardiogram is to record electrical activity caused by heart each cardiac cycle from body surface, and magnetocardiogram is record electrocardio electric current
Generated magnetic signal.Both comparisons, there is following characteristics:First, ecg measurement is to be attached to two electrode slices of body surface
Between potential difference, which is that electrocardiosignal have passed through human body conduction, nonlinear change have occurred obtain, it is impossible to accurate
The distribution of internal electrocardio electric current is extrapolated, and the nonlinear change that mcg-signals generate after each organizational communication of human body is smaller, institute
The magnetocardiogram measured can directly react the magnetic signal of electrocardio electric current generation.Secondly, electrocardiogram can only measure the current signal of alternation,
The current signal of direct current cannot be measured, and magnetocardiogram can measure magnetic field signal caused by alternation and DC current signal simultaneously.
In addition, ecg measurement needs electrode slice being attached to body surface, record is 2D signal, and the measuring device of magnetic chart is not
Need to contact human body surface, therefore magnetic measuring device can move to obtain three-dimensional magnetic chart in three dimensions, comprising letter
It ceases more rich.Compared with electrocardiogram, magnetocardiogram can preferably react heart body and its variation.
Since biopotential signals are at mV grades, the biological magnetic signal being generated by it is smaller.According to Biot-Savart law,
The intensity and distance in magnetic field(Refer to the distance of test point and magnetic field sources)Cube be inversely proportional, it is raw after the transmission that have passed through human body
Object magnetic signal is significantly decayed, extremely faint, for example core field intensity is about 10-10T is about 10 with geomagnetic field intensity-4T-phase ratio,
Intensity is about hundred a ten thousandths in earth magnetic field, therefore extremely difficult to its detection.It is applied in vitro at present to carry out
The equipment of so faint biological Magnetic testi has Superconducting Quantum interferometer, it is a kind of equipment that can measure faint magnetic signal, main
It is that magnetic flux is converted to voltage signal to want principle, is mainly used in the biological magnetic measurement such as heart magnetic and brain magnetic, but input now
The Superconducting Quantum interferometer used needs mating magnetic shield room and liquid nitrogen is used to cool down, inconvenient to use and costly.In life
Many fields of object Magnetic testi, for example in the Magnetic testi of stomach, intestines, oesophagus, nasal cavity etc., magnetic measurement is not yet widely used in clinic.
Main cause is because vitro detection instrument use cost is excessively high, and precision is limited.
If magnetic reception device can be extend into the inside that human body is detected biological tissue, it can effectively shorten biology
Magnetic signal greatly improves the intensity of magnetic signal, improves signal-to-noise ratio, therefore can improve magnetic distribution map to the distance of magnetic reception device
Accuracy of detection, the instrument of the biological magnetic signal of detection can also be simplified and using complexity.However, magnetic reception device is extend into
In tissue, certain discomfort can be brought to patient during the inspection process, but the medical inspection of this interior spy formula has elder generation
Example, for example, originating from 1795, start to be promoted in eighties of last century and needed with widely applied endoscope, when inspection by optics
Instrument endoscope extend into patient's body, and image is passed back, although these inspections can bring some uncomfortable to patient, it
The early detective rate of many major diseases is improved, therefore with important clinical meaning.
